<p><em>In line with the implementation of development in Indonesia, whose main target is in the field of economic development, trade activities are one of the sectors of economic development, constantly developing their role. Therefore, it is necessary to have adequate transportation facilities, both by land, sea, and air. The dynamics of the construction can be seen clearly both in terms of the number of high-rise buildings, vehicles, activity facilities, residential areas, and other infrastructure. This condition requires careful, fast, and precise anticipation from the Regional Governent and various policies in a spatial structure feasibility plan that considers the ability of transportation support as one of the main supports. This study seeks to study and analyze the related handling of idle time at PT Samudera Indonesia Jakarta by optimizing loading and unloading activities on container ships. By using descriptive qualitative methods and samples taken from PT Samudera Indonesia Jakarta, the following results are obtained: Problems in the system The cargodoring are: Difficult to direct the location of container dropping from the ship, The slow process of container dropping from the ship, Limited number of cranes, The occurrence of transportation queues, Limited ability to carry containers for each transport, Required trucks in large quantities, There was a clash between trucks that carry out the process of loading and unloading containers, the difficulty of directing the location of containers if it must be stacked with other containers, the development idea is to make a cargodoring handling system using a headless semi-automatic train, which utilizes seawater power and the conveyor system.</em><em></em></p><p> </p><em>Keywords : <strong>Idle time,</strong><strong>Optimization, Loading, Container, Samudra Indonesia</strong></em>
